技术领域
本申请涉及家用电器技术领域,更具体地,涉及一种推出机构和洗碗机。
背景技术
在相关技术中,使用蜡马达作为推出机构,蜡马达在使用时需要通电使内部液体受热膨胀,推动推杆运动将洗碗机的门体顶开,蜡马达发热严重,易导致安全风险,且蜡马达是较精密的微型机械,制造效率较低,会限制洗碗机的产能提升。此外,蜡马达的推杆在断电后需要等待自然冷却缩回,时间较长,冷却时间内一直保持顶出状态,用户无法关上洗碗机的门体,降低了用户体验。

下面参考附图描述根据本申请实施例的推出机构100,推出机构100可以应用于洗碗机、洗衣机等,下述以洗碗机为例。
参照图1-图8所示,根据本申请实施例的洗碗机包括本体、门体与根据本申请实施例的推出机构100,本体内具有洗涤腔室,门体设在本体上,门体可以打开或关闭洗涤腔室。在门体打开洗涤腔室时,用户便于向洗涤腔室内取放餐具;在门体关闭时,洗碗机可以进行工作,对洗涤腔室内的餐具进行洗涤。推出机构100可以设在本体或者门体,且推出机构100可以包括:电机20、第一驱动件40与推杆50。
具体而言,电机20可以包括限位部611,限位部611具有第一位置与第二位置。在电机20处于通电状态时,限位部611可以位于第二位置;在电机20处于断电状态时,限位部611可以位于第一位置。第一驱动件40可以与电机20传动连接,使得第一驱动件40可以在电机20的驱动作用下进行转动;或者,第一驱动件40可以与电机20脱离连接,使得第一驱动件40可以不受电机20的驱动作用。第一驱动件40可以设有止挡部411,止挡部411可以与限位部611相抵,由此,通过止挡部411与限位部611相抵,可以控制第一驱动件40停止转动。
可以理解的是,在电机20处于通电状态时,限位部611能够位于第二位置,第一驱 动件40在转动过程中,第一驱动件40上的止挡部411会根据第一驱动件40转动而跟随移动,在第一驱动件40转动到限位部611与止挡部411配合时,第一驱动件40可以通过限位部611的止挡停止转动,但是第一驱动件40具有继续转动的趋势;在限位部611没有与止挡部411配合时,第一驱动件40可以继续转动,直至限位部611与止挡部411发生配合。在电机20处于断电状态时,限位部611能够位于第一位置,第一驱动件40在转动过程中,限位部611与止挡部411不会发生配合,使得第一驱动件40可以不受限位部611的控制。
推杆50可以与第一驱动件40传动连接,使得推杆50可以在第一驱动件40的驱动作用下进行移动;或者,推杆50可以与第一驱动件40脱离连接,使得推杆50可以不受第一驱动件40的驱动作用。从而,通过推杆50与第一驱动件40传动连接与脱离连接,能够使推杆50可以具有伸出状态和缩回状态。
在推杆50处于伸出状态时,推杆50可以与门体或者本体止抵,使推杆50可以通过推动门体或者本体止抵,能够打开门体,从而打开洗涤腔室。通过在洗涤程序的干燥阶段将洗涤腔室打开,可以使洗涤腔室内的湿热蒸汽排到外部,能够增加洗涤腔室的空气流动,加速水汽蒸发过程,从而实现洗碗机降低功耗、提升干燥效果的目的,且避免了手动打开门体需要用一定外力拉动的问题,使用户在使用时更方便,提高了用户体验;在推杆50处于缩回状态时,推杆50可以不影响门体的关闭,便于关闭洗涤腔室。
由上可知,所谓传动连接即动力传递,将自身的运动传递至另一方,可以直接传动也可以间接传动,而脱离连接即断开动力的传递。第一驱动件40中的“驱动”之意在于相对于推杆50而言,第一驱动件40通过传动连接能带动推杆50发生动作(下文中的第二驱动件70中的“驱动”亦是如是)。
推出机构100在运动过程中,推出机构100可以具有第一状态、第二状态、第三状态与第四状态:
推出机构100在第一状态时,如图6所示,电机20通电后,电机20可以与第一驱动件40传动连接,第一驱动件40可以与推杆50传动连接。从而,电机20可以带动第一驱动件40转动,第一驱动件40转动可以带动推杆50运动,使得推杆50由缩回状态切换至伸出状态,推杆50与门体或者本体止抵,能够使推杆50推动门体打开洗涤腔室。通过各个部件传动连接实现推杆50推出,与蜡马达作为推出机构的相关技术相比,本申请没有发热部件,避免了部件发热而造成安全隐患,保证了推出机构100的使用安全性。
推出机构100在第二状态时,如图2所示,电机20继续保持通电,电机20可以与第一驱动件40传动连接,第一驱动件40可以与推杆50脱离连接。从而,电机20可以带动第一驱动件40转动,推杆50可以不受第一驱动件40的驱动作用,使得推杆50可以可由伸出状态切换至缩回状态,在推杆50处于缩回状态时,能够便于用户关闭门体。通过第一驱动件40可以与推杆50脱离连接,即可实现推杆50缩回,避免了相关技术中蜡马达作为推出机构需要等待自然冷却的缺点,通过使推杆50脱离连接,即可使用户在需要关闭门体时将门体关闭,不需要长时间等待,使用户具有较好的使用体验。
推出机构100在第三状态时,如图8所示,电机20继续保持通电,电机20可以与第一驱动件40脱离连接,且限位部611可以与止挡部411相抵,从而,第一驱动件40可以不受第一驱动件40的驱动作用,同时第一驱动件40可以在限位部611的阻挡下停止转动,避免了第一驱动件40持续转动使得第一驱动件40再次与推杆50传动连接,确保在电机20通电时推杆50只会顶出一次,不影响洗碗机的后续操作。同时,通过电机20与第一驱动件40脱离连接,使得第一驱动件40在限位部611的阻挡下停止转动后,第一驱动件40不会受到电机20与限位部611的双重作用而造成结构损坏,能够不影响电机20的正常工作,保证了电机20的使用安全性。
推出机构100在第四状态时,电机20断电,限位部611位于第一位置,使得限位部611可以与止挡部411分离,第一驱动件40可以继续转动,从而使电机20可以重新与 第一驱动件40传动连接,且使第一驱动件40可以重新与推杆50传动连接,或者在电机20再次通电时,第一驱动件40能够与推杆50传动连接,使得推出机构100可以由第四状态切换至第一状态,能够开始下一个运动循环,运动过程如上所述,这里不再详述。
本申请的发明人发现,相关技术中,推杆需要通过传感器等控制系统检测位置,并且通过检测到的推杆位置控制电机的通断。
而在本申请中,电机20可以一直保持通电状态,在推出机构100处于第三状态时,通过电机20可以与第一驱动件40脱离连接,限位部611可以与止挡部411相抵,能够在电机20处于通电状态下,第一驱动件40可以不受电机20的控制,且在限位部611与止挡部411配合作用下,第一驱动件40可以停止转动,能够进一步避免第一驱动件40与推杆50传动连接从而推出推杆50,实现电机20通电一次,推杆50可以推出一次的效果,省去了传感器等控制系统对推杆50的位置进行检测以控制电机20的断电,使推出机构100的电路简单,降低了内部结构的复杂性,从而降低了生产成本。
在一些实施例中,推出机构100可以通过定时实现对电机20的通断电控制,而时间可基于现有电控电路进行设置即可。在电机20通电时,推出机构100可以在控制时间内完成第一状态、第二状态、第三状态与第四状态,确保推杆50可以由缩回状态切换至伸出状态,能够推开门体打开洗涤腔室,且再由伸出状态切换至缩回状态,不影响门体的关闭,同时对下一次的运动循环做准备,完成上述动作,到达时间后,对电机20断电,控制简单。
根据本申请实施例的推出机构100,通过传动连接能够实现推杆50推出,且在第一驱动件40与推杆50脱离连接时实现推杆50缩回,避免了相关技术中蜡马达作为推出机构需要等待自然冷却使推杆缩回的缺点,传动连接发热少,避免了发热而造成安全隐患,保证了使用安全,使用户具有较好的使用体验。通过第一驱动件40可以在限位部611的阻挡下停止转动,使电机20通电时推杆50只会顶出一次,省去了传感器等控制系统对推杆50的位置进行检测以控制电机20的断电,使推出机构100的电路简单,降低了内部结构的复杂性,从而降低了生产成本。
根据本申请的一些实施例,推出机构100在第三状态时,第一驱动件40与推杆50可以脱离连接,从而在第一驱动件40与电机20脱离连接后,能够避免推杆50对第一驱动件40的转动产生影响,确保第一驱动件40转动顺畅。
在本申请的一些实施例中,如图2-图8所示,电机20可以包括定子21和转子22,转子22可转动地设在定子21内,转子22可以与第一驱动件40传动连接,使得第一驱动件40可以在转子22的驱动作用下进行转动;或者,转子22可以与第一驱动件40脱离连接,使得第一驱动件40可以不受转子22的驱动作用。定子21可以包括第一定子61,第一定子61可以设有限位部611。在电机20处于通电状态时,第一定子61可以位于第二位置,电机20在断电状态时,第一定子61可以位于第一位置,也即第一定子61为可动定子,通过对第一定子61进行控制可以实现对限位部611进行控制,使得电机20结构简单。
在电机20处于通电状态时,如图4所示,第一定子61可以位于第二位置,此时,限位部611与止挡部411可配合。第一转动部41在转动过程中,第一转动部41上的止挡部411会根据第一转动部41转动而跟随移动,在第一转动部41转动到限位部611与止挡部411配合时,第一转动部41通过限位部611的止挡停止转动;在限位部611没有与止挡部411配合时,第一转动部41会继续转动。

另外,在向线圈63通入交流电时,线圈63产生的磁场可以使转子22开始转动,使转子22可以带动第一驱动件40转动;在线圈63断电时,线圈63产生的磁力消失,转子22停止转动。

在线圈63通电时,第一定子61受线圈63磁力作用吸合,对第一弹性件211进行压缩,第一定子61位于第二位置,第一弹性件211对第一定子61具有向相反方向移动的趋势;在线圈63断电时,线圈63磁力消失,第一定子61可以在第一弹性件211的弹性形变作用下,对第一定子61施加作用力,使得第一定子61移动到第一位置。通过第一弹性件211驱动第一定子61移动到第一位置,结构简单,避免了控制组件的使用,降低了生产成本。例如,第一弹性件211可以为弹簧等。
